Rudder

Hello,
Sorry if i don't know the basic of a how to fill a "bug report"
I was trying to create a cron job with the directive on rudder 4.3.2, and was rejected because my user didn't match standard.
In deed my user have a "-" in them. i understand that it is better to follow standard, but it would be nice if they was a way to "force valide".

Exact error message :
Please modify User to run the command as to match the requested format : Please enter a valid user name
Exact user name :
rmt-script
Technique version :
cron jobs 3.1

Thank's
